lifting its ban on women serving in combat. the official announcement will come tomorrow from secretary of defense leon panetta. we asked david martin at the pentagon to tell us more about what this will mean. >> reporter: the defense secretary's order will make women eligible to serve as infantrymen on combat patrol and even in elite special operations units like the navy seals. however, women will have to meet strength standards that could keep them out of units where the physical demands are especially grueling. combat operations in iraq and afghanistan have already cost more than 130 women their lives and left more than 800 wounded. some, like dawn halfaker, were on the front lines commanding an m.p. platoon in iraq where she lost her arm fighting alongside the infantry. >> there's not a big difference at all. and a lot of the missions we did we did with infantry units. we would do with field artillery units. we were all fighting the same fight, doing the same thing. >> reporter: the best machine

gunner in halfaker's platoon was victoria rivers, who was tapped to go on missions with special forces. >> working side by side with special forces teams was pretty cool. >> reporter: but rivers acknowledges some military jobs may be too demanding for women. >> there's jobs that women can't do physically because they just don't have the strength, the physical strength to do it. >> reporter: the marines recently opened their infantry officer school to women but the first two dropped out. in the army, an infantryman carries a 63-pound pack which could go to more than 100 pounds depending on the situation. panetta's order will open 200,000 more jobs to women primarily in the army and marines where combat experience is considered a prerequisite for promotion to the top jobs. the services will have until may to draw up a plan for opening all units to women and until the end of the 2015 to actually implement it.

if the military wants to keep units like navy seals or army green berets off limits to women, they will have to justify it directly to the secretary of defense. >> pelley: david, thank you. how four americans were killed last september in libya was the subject of testimony by secretary of state hillary clinton today, and her long- awaited appearance before congress was remarkable as secretary clinton confronted some sharp questioning. one senator said that she should have been fired. on the last anniversary of 9/11, terrorists attacked the u.s. consulate in benghazi and killed embassy staff, including u.s. ambassador chris stevens. our state department correspondent, margaret brennan, was in the hearing. >> as i have said many times, i take responsibility. >> reporter: in her opening statement, the usually reserved hillary clinton said that for her the benghazi tragedy is personal. >> i stood next to president obama as the marines carried those flag-draped caskets off the plane at andrews.

i put my arms around the mothers and fathers, the sisters and brothers, the sons and daughters and the wives left alone to raise their children. >> reporter: secretary clinton said that while she had a close relationship with ambassador chris stevens, his request for additional security never made it to her desk. >> the specific security requests pertaining to benghazi were handled by the security professionals in the department. i didn't see those requests. they didn't come to me; i didn't approve them, i didn't deny them. >> reporter: still, republican senator rand paul said she should be held accountable. >> had i been president at the time and i found that you did not read the cables from benghazi, you did not read the cables from ambassador stevens i would have relieved you of your post. i think it's inexcusable. >> reporter: clinton said she constantly thinks of what could have been done earlier. >> you know, i do feel responsible. i feel responsible for the nearly 70,000 people who work

for the state department. i take it very seriously. >> reporter: republican ron johnson accused the obama administration of covering up the nature of the attack in the weeks following the assault. >> we were misled that there were supposedly protests and then something sprang out of that, an assault sprang out of that. and that was easily ascertained that that was not the fact, and the american people could have known that within days and they didn't know that. >> with all due respect, the fact is we had four dead americans! was it because of a protest or was it because of guys out for a walk one night who decided they'd go kill some americans? what difference at this point does it make? it is our job to figure out what happened and do everything we can to prevent it from ever happening again, senator! >> reporter: clinton focused her testimony on her efforts to fix security issues at the state department. she pointed out that while security costs have gone up, congress has refused requests for more money and cut the state department budget. senator john mccain, a critic of the administration's response to

the attacks, said clinton's answers were unsatisfactory. >> the american people and the families of these four brave americans still have not gotten the answers that they deserve. i hope that they will get them. >> reporter: secretary clinton connected what happened in benghazi to the rise of al qaeda splinter groups in nearby mali and the recent terrorist attack in algeria. she warned the events are linked. instability in north africa has opened a pandora's box of threats against the united states. >> pelley: margaret, thank you. one man who will be called in to deal with those threats is general john allen, and we learned today that president obama will resubmit allen's nomination as commander of nato forces in europe. the pentagon investigated general allen for sending potentially inappropriate e- mails to a florida woman linked to the david petraeus scandal, but yesterday allen was cleared of wrongdoing. the battle over the debt ceiling

has been put off to another day because on this day the republican-controlled house voted 285-114 to allow the government to keep borrowing the money it needs to pay its bills through mid-may. the senate and the white house are expected to go along avoiding the threat of default that would rattle financial markets. in a survey of investors by bloomberg, 36% said america's fiscal woes are the biggest threat to the world economy, more than the 29% who named the european debt crisis. anthony mason is attending a meeting of world bankers in davos, switzerland. >> reporter: how strong do you think the u.s. economy actually is right now? >> i think the u.s. economy wants to be strong. >> reporter: but mary callahan erdoes says the bickering in washington is holding it back. erdos is one of the most powerful women on wall street. as c.e.o. of j.p. morgan asset

management, she presides over $1.2 trillion in investments. >> the u.s. has to realize it's got so much going for it. let's just get ourselves to come together as a team, one team running that country, helping to get itself back on stable footing which then cascades to the rest of the world. >> reporter: how much does it hurt the economy if we don't confront this? >> it hurts us tremendously. it hurts the confidence of the u.s., it hurts the confidence of the c.e.o.s to know how do i invest? what are the rules going to be? and we've got to get back to believing that business is good. american business is good. >> reporter: erdoes is making her fourth trip to the world economic forum in davos. the talk here is of recovery. does the atmosphere feel a little better this year? >> it feels much more hopeful. i mean, it was just a year ago we were talking about country defaults and company defaults. >> reporter: in europe now they're looking at the u.s., wondering why washington is so hopelessly gridlocked.

as one columnist here put it "the u.s. economy now carries a permanently heightened level of political risk." do you think that's an exaggeration? >> i think when you listen to the people in davos who aren't from america, that's what they think. they watch the t.v.s and they read the newspapers, and that's sort of all they hear. and we need to get that off of the headlines, and we need to go back to looking at these great companies that are some of the leaders of the industries of the world. >> reporter: but overall here in davos, the mood is markedly more upbeat this year. among the hundreds of corporate chairman and c.e.o.s, there's a growing sense that after four years of dealing with the fallout from the financial crisis, they've finally turned the corner. >> pelley: anthony, i'm curious, what are some of the other dangers to the world economy that are being discussed out there? >> reporter: well, one looming economic threat that's been raised, scott, is actually global warming. the head of the international monetary fund, christine

lagarde, in a speech tonight said she sees global warming as the wild card that could unravel economic growth. and if we don't deal with it, in her words, the next generation could be "roasted, toasted fried and grilled." >> pelley: hard to imagine in chilly davos, but thank you very much, anthony. thank you again. there is no relief from the deep freeze in the northern states. a ski resort in new hampshire shut down today because it was too cold to ski. it got down below 27 below zero this morning in northern minnesota. fire met ice in chicago. 170 firefighters, a third of the force, battled flames at an old warehouse. all that water froze on the building, giving it the look of a crystal palace. the arctic blast couldn't come at a worse time for people who still aren't back in their homes three months after superstorm sandy. elaine quijano has more on that.

>> reporter: we found anthony gambino inside a tent run by volunteers on staten island. the temperature outside was in the 20s. when you felt that cold, what went through your mind? >> find warmth and find it fast, and here it was. >> reporter: gambino has been sleeping here off and on since sandy severely damaged his home. the former mechanic lives on disability. this is how you sleep? >> fine, right here. folding chair here, got the t.v., got the heat, it's all good. >> reporter: one of the volunteers is tim chin. these are your supplies? >> these are the supplies that we have. >> reporter: he's given out 70 space heaters in the last couple of days. >> it's been getting really, really, really crazy with the heaters. people are freezing. they're cold, and we're trying our best to meet the needs of the community which is keeping them warm for the next few days as it gets colder and colder. >> next week, they're talking about getting warmer. but let's face it, we're going into february; february is unpredictable, march is unpredictable. we may get worse; we may get better, who knows?

right now, we've got to deal with the moment, and the moment is bad. >> reporter: anthony gambino will sleep here once again tonight. scott, in new york and new jersey, there are at least 2,400 people still living in shelters or hotel rooms because of the storm. >> pelley: lows are going to be in the 20s all week. thank you very much, elaine. new research is revealing the heavy toll that smoking is taking on women. what happens when a city makes severe cuts to its police force? and they served america well; now they may be headed for retirement. when the "cbs evening news" continues. retirement, when the "cbs evening news" cont look what mommy is having. mommy's having a french fry. yes she is, yes she is.

sexual abuse, and, according to the c.d.c., nearly one in five women has been raped. and in more than half of those cases, the rapist was an intimate partner. today, america's ob-gyns put out guidelines to help doctors deal without sexual abuse, and jon lapook is here to talk about that. >> they're talking about other forms of abuse including birth control sabotage. that's where a man interferes with a woman's contraception for example, by poking holes in condoms and throwing away birth control. a study found that 15% of women reported birth control sabotage. >> pelley: is there any research that would indicate why a man would do that? >> i spoke to a doctor who's an expert, and she said it's about power, about a man controlling a woman's body. and a man who do this is much
